Sedimentary Rock. The sedimentary rocks are formed by the deposition and subsequent cementation of that material within bodies of water and at the surface of the earth. The process that causes various organic materials and minerals to settle in a place is termed as sedimentation. The particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, the ...
